You know the room. Maybe it’s on the second floor. Maybe it’s in your basement. It’s always cold no matter what you do. You open the door to the hallway. You make sure the vents are open. Finally, you crank up the heat. Now, the room is still cold, and the rest of the house is like a hot sauna.
Many Menomonie homeowners assume the only answer is a new HVAC system. But can you add zoning to an existing ducted system? In many homes, yes. By adding zoning controls to your home’s HVAC system, you can finally make that room comfortable without installing a new HVAC system.
An HVAC zoning system allows you to send conditioned air to different areas. However, zoning may not be suitable for every HVAC system. Your ductwork, equipment, airflow and existing controls should be assessed before adding zoning.
How Does an HVAC Zoning System Work?
HVAC zoning systems separate a home into different comfort areas. Each zone has its own thermostat. Motorized dampers inside the ductwork control how much conditioned air reaches each area.
A zone control system for your HVAC means you can set different temperatures for each zone. Instead of treating the entire house as one space, the precise temperature control with a ducted zoning system creates customized comfort.
Can an Existing Ducted HVAC System Be Zoned?
Many homes benefit from adding zoning to an existing HVAC system. However, not every system is well suited for HVAC zoning.
To find out if zoning is ideal for your home, a professional evaluation should consider several factors:
- Current air duct layout: Ducts must be able to support separate zones.
- Current equipment: Some HVAC systems work better with zoning controls than other systems.
- Blower size: The blower must be capable of managing changing airflow as dampers open and close.
- HVAC system age: Older equipment may have limitations that affect zoning compatibility.
- Control board compatibility: The equipment must be able to communicate properly with the new controls.
- Ductwork accessibility: Technicians need be able to reach your ductwork for damper and wiring installation.
- Number of zones: More zones typically make the installation more complex.
An HVAC professional should evaluate your existing system before recommending zoning installation.
7 Reasons Your Home Might Benefit from Adding Zoning
If your home has these common comfort problems, they are signs that zoned heating and cooling might be able to help:
- Upstairs stays hotter than downstairs: Multi-story homes often have varying heating and cooling needs. Zoning can help deliver conditioned air to the areas that need it most.
- Finished basements are always chilly: Because they are below ground, basements are often colder than main floor and upper story rooms. A separate zone can help address those differences.
- Rooms with large windows overheat: Solar heat gain can cause these rooms to become uncomfortably hot.
- Extra rooms above garages: These spaces often have different temperature demands.
- Additions never stay comfortable: An addition may have unique ductwork or greater exposure to outdoor temperatures.
- Family members fight over the thermostat: Separate zones can make it easier to accommodate different temperature preferences among family members.
- West-facing rooms become much warmer: Sun streaming through large windows, especially on the west side of a home, can make rooms uncomfortably hot at the end of the day.
Benefits of Adding HVAC Zoning
HVAC zoning benefits begin with improved comfort. Zoning can provide more consistent temperatures and customized settings. It also is designed to eliminate the need to overheat or overcool some rooms to make other rooms a more comfortable temperature.
Depending on the home, zoning supports better energy efficiency and limits unnecessary system runtime. However, energy savings are not guaranteed, and correct system design is important.
When Zoning May Not Be the Best Solution
Zoning isn’t isn’t always the best solution for every home. Before investing in a home zoning system, an HVAC professional should find out what is the cause of uneven temperatures or other comfort problems in the home.
Poor insulation, air leaks, damaged ductwork and improper system design can cause rooms to be warmer or cooler than they should be. Oversized or undersized equipment can also cause issues that zoning alone cannot correct. Poor airflow, dirty filters and closed registers should be corrected before considering zoning.
In some homes, strategies like HVAC airflow balancing or making duct repairs may be a more effective approach than adding zoning controls.
What Happens During a Zoning Installation?
Professional HVAC zoning installation begins with evaluating your home, testing airflow and inspecting the ductwork to determine where zones and dampers should be placed.
Installation includes installing motorized HVAC dampers in your duct work, thermostats and control wiring. The technician then tests the individual zones and adjusts the system. Installation time varies based on duct accessibility, number of zones and system complexity.
Is HVAC Zoning Worth It?
If your upstairs is consistently warmer than downstairs or your home has other stubborn comfort differences, zoning could be a worthwhile option. HVAC zoning cost in your home depends on factors such as the number of zones, ductwork modifications and controls.
The best way to find out if zoning is right for you is to have an experienced HVAC contractor like Halverson Brothers Inc inspect your home and existing HVAC equipment. Our team will evaluate your ductwork, equipment, airflow and controls and determine the right approach.
